I have carefully read the documentation (man slapd-sql) but could not
find how to modify the attribute mapping and add a "type" flag.
I meant: modify the code. Since back-sql is basically unmaintained (any
volunteers out there?) this feature won't likely be added, not to mention
the fact that it would break all existing installations.
